previous plantings show no evidence of seedling emergence. This third planting is <br /> a continuing effort to establish this material via direct seeding. Rows were laid out <br /> east to west on the north side of several spruce trees. Soil was moist in direct <br /> sunlight and muddy in the shade. Foot packing was done prior to belt seeding. <br /> Seeding depth was approximately one quarter to one half inch. Seeding rate was <br /> heavy; the V-belt of the belt seeder was filled to capacity and soil was added as a <br /> carrier and to prevent the seed from blowing out of the belt. It was felt that cooler, <br /> moister soil conditions may mimic natural site characteristics more closely at the <br /> time of floret shatter and when the species naturally seeds itself. <br /> An additional single row planting was done in the bare root field using a hand held hoe. <br /> Seed was sprinkled along the twenty foot row and covered and lightly packed. <br /> Germination and Purity Determination <br /> Germination trials were conducted by UCEPC's plant propagationist on Lot 1 seed (drill <br /> ready). Test results indicated a 48 percent germination of this seed which was more than <br /> adequate to pursue a field planting for this seed increase project. Purity was calculated by <br /> taking four samples of seed ranging from 117 seeds in one sample to 368 seeds in a <br /> second sample, weighing each sample as bulk seed and as cleaned seed, and averaging. <br /> Calculations determined that seed weight was 1475 seeds per gram without callus hairs <br /> and that 31% of a sample by weight was clean seed. Taken with the germination results, <br /> the PLS factor for the seed was (0.31 x 0.48) 0.15. <br /> Seeding rate calculations were done and packets prepared for use in the "cones" of the <br /> Cone Seeder. Four 470 foot rows with 36" row spacings figures out to 0.13 acre. <br /> • 470 ft row x 3 ft row spacing = 1410 square feet <br /> • 1410 square feet/43560 square feet/acre = 0.03 acre/ row <br /> • 0.03 acre/ row x (4 rows) = 0.1295 acre <br /> Total Planting <br /> Planet Junior 0.09 acre <br /> Cone Seeder 0.13 acre <br /> 0.22 acre <br /> Seeding Rate Calculations <br /> Our desired seeding rate was 30 pure live seeds per linear foot. Accounting for <br /> germination of 48 percent and purity of 31 percent, our PLS factor is 0.15. <br /> 30 PLS x 0.15 = 200 "seeds" by weight per linear foot of planting <br />
